OK. It wasn't so simple.  
Anyway, what is the transmitter going to do ? You haven't got many pins left on the MCU for much other activity. I suppose it could send its own battery voltage back to the receiver and, maybe temperature.

Incidentally, a much nicer pinout diagram can be found here without hunting through .h files: [megaTinyCore/ATtiny\_x12.md at master · SpenceKonde/megaTinyCore · GitHub](https://github.com/SpenceKonde/megaTinyCore/blob/master/megaavr/extras/ATtiny_x12.md)
